CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 570,876,6lated November3, 1896.

Application filed July 9, 1895. Serial No. 555,385. (No modeld To allwhom, it may concern:

Be it known that I, AUGUSTUS L. LE GRAND, a citizen of the UnitedStates,residing at Pittston, in the county of Luzerne and State ofPennsylvania, have invented a new and usep ful Conveying Apparatus, o fwhich the folapparatus.

Y sprocket-wheel for driving the same.

lowing is a specification.

This invention relates to conveying apparatus; and it has for its objectto provide an improved swinging or laterally-ad j ustable apparatus ofthis character designed for removing and screening material fromculm-banks, sand-banks, and the like, and, as the banks are removed, tobe adjusted toward the embankment without disarranging the driving oroperating mechanism for the conveyer.

The invention also contemplates, as a special .feature thereof, meansfor screening the material, so that the ne and coarse material will beconveyed in different directions or. to different points of deposit, andin this ad aptation of the apparatus the same is especially useful inconnection with sand banks to screen the sand from the gravel and inconnection with anthracite-onlin banks to screen the rock, slate, andlarger particles from the finer particles of the bank.

With these and other objects in view,which will readily appear as thenature of the invention'is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the drawings, Figure l is a top plan View of a conveying apparatusconstructed in accordance with this invention, shownas arranged inoperative relation to a culm or sand bank. Fig. 2 is a side elevation ofthe same. Fig. 3 is an enlarged detail side elevation, partly insection, of a portion of the Fig. 4 is an enlarged detail verticalsectional view on the line 4 4 of Fig. 3. Fig. 5 is a plan view of theturn-table. Fig. Gis an enlarged detail elevation of a short section ofthe tlighted conveyer and the` Fig. 7 is an enlarged detail transversesectional view on the line 7 of Fig. 3. Fig. Sis an enlarged detailsectional View showing a modied construction of pivotal support for oneend of the conveyer-frame. Fig. 9 is an enlarged detail sectional Viewof the turn-table.

Referring to the accompanying drawings, 1 designates a laterally orhorizontallyswinging horizontal conveyer-frame built in anysuitablelength, according to the size of embankment in connection withwhich the same is designed to be employed. The frame l is referred to asbeing a horizontal frame and adapted to swing in a horizontal direction,and in this connection it will be understood that when the apparatus isused on perfectly level ground or on a level surface the same will thenbe truly horizontal and will swing horizontally toward the embankmentfrom which the material is being taken, but in use the apparatus willnecessarily be employed at times on uneven surfaces and even ondeclivities. In such cases the conveyer-frame l and the movement thereoflaterally will be approximately horizontal, and therefore the termhorizontal is to be understood, in a relative way,with reference to theuse of the apparatus as working directly over the surface of the groundirrespective of the level thereof. The said laterally or horizontallyswinging conveyer-frame l supports therein a pair of horizontal upperand lower conveyer-troughs 2 and 3, respectively, which extend from endto end of the conveyer-frame. The upper and lower conveyer-troughs 2 and3 are arranged one directly above the other and extend in parallelplanes, so as to operate in conjunction with each other for the purposeof receiving different portions of the material to be conveyed to apoint of deposit, as will be particularly referred to. Both of theconveyer-troughs, which extend the entire length of the swingingconveyerframe, are open at the top and are provided with oppositeinclined sides 4, and the upper of said conveyer troughs, 2, is providedthroughout the length thereof with screensections or a series ofscreen-bars 5, which allow the liner portions of the material, which isshoveled into the upper trough, to screen or sieve through the saidupper trough and into the lower trough 3, which is provided with aclosed bottom, sovthat the finer portions of the material may beconveyed through the IOO ' the pivoted end of the conveyer-frame.

lower trough 3 in one direction, while the coarser portion of thematerial is conveyed through the upper trough 2 in an opposite directionto a separate point of deposit.

The horizontally or laterally swinging conveyer-frame 1 has fitted tothe lower side thereof at suitable points supporting-rollers 6, whichare arranged to travel on the trackrails 7, arranged below theconveyer-frame, and providing means, in conjunction with thesupporting-rollers, to permit the conveyerframe to be freely swungtoward the embankment as the same decreases in size. The frame lis alsoprovided at one extremity with the lateral extensions or timbers 8, thatare rigidly fastened on top of the rotary turntable plate 9. The rotaryturn-table plate 9 is supported for a fixed rotation on the stationarybearing-plate 10, which is mounted on a stationary supporting base-frame1l, which base-frame provides a firm support for The said stationarybearing-plate l0 is provided with a circular bearing-iiange 12, whichfits at its upper edge inside of the short depending rim or flange 13,formed at the periphery of the rotary turn-table plate 9, and providingmeans to assist in holding the plate 9 perfectly steady in its rotation.The bearing-plate l0 is provided on its upper side with a circularbottom track 14, on which travel the vertically arranged supportingwheels or rollers 15, mounted in the bearingbrackets 16, fastened to theunderside of the rotary turn-table plate 9, and on the inner side ofyits upwardly-disposed flange 12 the plate 10 is also provided with acircular side track 16, against which travel the horizontally disposedside Wheels or rollers 17, mounted in the bearing-brackets 18, securedto the under side of the plate 9, near its edge. The rollers 15 and 17provide for the free pivotal support of the plate 9, and also for theiirm bracing thereof, so that the plate will freely rotate in a fixedcircular plane.

The rotary turn-table plate 9 is provided centrally on its upper sidewith a bearing-step 19, in which rotates the lower end of the verticalpivot-shaf t 20. The vertical pivot-shaft 20 has itted on the upper endthereof the horizontal beveled gear-wheel 21, which meshes with abeveled gear-pinion 22, mounted on one end of the drive-shaft 23, whichis driven by means of suitable belting to provide for transmittingmotion to the vert-ical pivotshaft 20. The said vertical pivot-shaft 2Ohas tted thereon directly above the bearing-step 19 a horizontal beveledgear-pinion 24, with which meshes a vertically-disposed beveledgear-wheel 25, `titted on one end of the horizontal headshaft 26. Thehorizontal headshaft 26 is mounted in suitable bearings 27 on theconveyer-frame 1 ,at the pivoted end thereof, so that as saidconveyer-frame is swung laterally the beveled gear-wheel 25 will alwaysmaintain its engagement with the pinion 24, which transmits motionthereto, and

the said head-shaft 26 has mounted centrally thereon avertically-disposed sprocket-wheel 28, over which passes an ordinarylink belt or conveyer-chain 29. The conveyer-chain 29 extends the entirelength of the conveyerframe 1, and at the end of the frame 1, oppositethe wheel 2S, the said chain passes over an idler chain or foot wheel30, iitted on the foot-shaft 31, mounted in suitable bearings at theunpivoted or swinging end of the conveyer-frame l. The upper horizontalportion of the conveyer-chain 29 runs in one direc tion in the uppertrough 2, and the lower horizontal portion of the conveyer-chain runs inan opposite direction in the lower trough 3, and fitted on theconveyer-chain 29 at regularly-spaced intervals are a series of conveyenflights 32, which travel directly on the bottom of the troughs 2 and andprovide means for pushing or conveying the material in the troughs toone end thereof.

Through the medium of the gearing described motion is transmitted totheendless conveyer consisting of t-he chain 29 and the flights 32, andin operating the apparatus the conveyer-troughs are swung to a positiondirectly adjacent to the bank of material, and the material is thenshoveled into the upper trough. The screen-sections of the upper troughallow the finer portion of the material to fall into the lower trough,so that the coarse material will be conveyed through the upper trough inone direction and the finer material will be conveyed through the lowertrough in an opposite direction. The coarse material which remains inthe upper trough 2 is carried toward the foot-wheel 30, and when itreaches a point directly adjacent to said wheel it discharges through alaterally-extending chute 33, communicating with the upper trough 2 andextending to a point over a supplemental conveyer 34. This supplementalconveyer 34 is arranged at one side of the swinging end of theconveyer-frame 1 and may be of any suitable construction for conveyingaway the material discharged from the upper trough 2. Vhen a culm-bankis being removed through the medium of the herein-described apparatus,the coarse material discharged from t-he trough 2 is carried by thesupplemental conveyer 34 to a breaker, Where .it is crushed, washed, andthe coal separated from the slate, while the iine portion of thematerial which falls into the lower trough 3 is conveyed through thelower tro ugh toward the pivoted or fulcrumed end of the conveyer frame,at which point the said lower trough has leading off from the bottomthereof a downwardlyinclined chute 35, which extends over the lower endof a supplemental inclined conveyer 36. veyer 36 is arranged to extendat an inclination beyond the pivoted or fulcrumed end of theconveyer-frame, and when the apparatus is employed for conveying onlinthe fine portions of material discharged from the trough 3 onto theconveyer 36 are carried by such The con- K IOO IIO

conveyer to the boiler-house, where it is used for fuel, and it willtherefore be seen that the purpose of the conveyers 34 and 3G is tocon.- vey the separate portions of the material to 'separate points ofdeposit.

The apparatus herein described is susceptible of modification, such asillustrated in Fig. S of the drawings, in which figure the rotaryturn-table plate` 9a is illustrated as being provided centrally on itsunder side with a rounded pivot-stud 37, turning in a bearingsocket 3S,formed in the upper side of the step-block 39, suitably secured on astationarysupporting base-frame l1. 4At this point v latches 42 with thecatches 43 the drop-doors 4l will be supported in theirclosed position,so as to prevent the material from screening through the screen-sectionsinto the lower trough 3, in order that all the material can be conveyedthrough the upper trough in the direction traveled by the upper iiightsof the conveyer. When it is desired to use both troughs, as described,the doors 4l are unlocked and allowed to drop down to uncover theopenings in which the screen sections or bars 5 are fitted, and in theevent of it being desired to convey all the material in the directiontraveled by the lower flights of the conveyer the material is allshoveled or otherwise mechanically placed into the lower trough, as willbe readily understood.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.
